OBJECTIVE:To provide references for pharmaceutical workers in retrieving literatures by means of Chinese bi_omedical database(CBM),China journal full-text database(CNK) and Chinese science & technology journal database(VIP).METHDOS:With the commonly research topics of hospital pharmacy as research scope,literatures retrieved by database sampling underwent a preliminary contrast analysis and a computer-assisted automatic meta-analysis after programming.RESU_TLS:None the 3 databases indexed all the tested pharmaceutical periodicals(totaled 79 kinds).There were differences among the un-indexed periodicals, except a few are the same in kinds.The retrieved literatures of docuterm had a high proportion of repetition;however,the computer had merged the same literatures retrieved in different databases.CONCLUSIONS:The literatures indexed in the 3 databases have their own characteristics,thus literature recall ratio can only be improved by combining multiple databases.The automatic meta-analysis of the retrieval literatures can be performed by means of computer program,the repeated work can be reduced thereafter.

Objective:To investigate the clinical efficacy and safety of antiplatelet combined with anticoagulation therapy for restenosis prophylaxis after stent placement in diabetic patients with leg atherosclerosis obliterans(LASO). Methods:83 diabetic LASO patients with stent placement were collected and randomly divided into the treatment group(42 cases)and the control group (41 cases)with 49 sick limbs in each. The control group was treated with clopidogrel(75mg,for 1 year)plus bayaspirin(100 mg),while the treatment group was treated with low molecular heparin(withdrawal when INR = 2. 0- 3. 0)plus warfarin(for 6 months)additionally. All cases were followed up for 12 months and the efficacy and safety were compared and evaluated. Results:After therapy,there were no differences in FPG,GHbA1C,TC and LDL-C at each time point between the two groups(P >0. 05). Compared with that in the control group,MLD in the treatment group was improved obviously(P < 0. 05)in the 12th month after the surgery,while restenosis rate and level of D-D in plasma were declined significantly(P < 0. 05). And there was no difference in bleeding rate between the two groups(P > 0. 05). Conclusion:Compared with antiplatelet therapy,antiplatelet combined with anticoagulation therapy for restenosis prophylaxis after stent placement in diabetic LASO patients is more effective and safer,which is worthy of clinical promotion.

Objective To understand the zoonotic trematode species identified in domestic animals from Huainan area,An-hui Province,so as to supply the evidence for the prevention of zoonoses. Methods The livestock/definitive hosts were commer-cially available on category basis,and sacrificed for obtaining the parasitic samples via dissecting the viscera. The specimens were microscopically identified,with reference to the descriptions in the previous literature. Results By identification,sorting and classification,41 species of internal trematodes were found so far in the domestic animals fed in Huainan areas,in which 23 spe-cies were zoonotic trematodes and 18 were internally parasitic in livestock,belonging to 4 orders,12 families and 21 genera,and occurred in 9 definitive hosts including chicken,ducks,geese,pigs,cattle,buffaloes,sheep,goats and dogs,respectively. Con-clusion The findings suggest that the zoonotic trematodes belong to many kinds and prevalent in the domestic animals in Huainan areas,and such prevalence should call for high attention since it is urgent risk factors for zoonoses in this geographic area.

BACKGROUND: The abnormality of the function of arcuate nucleus may be an important factor of obesity. It has been known that the mechanisms of acupuncture in treating obesity are related to nervous and neurohumoral regulation. What is the regulating effect of acupuncture on the function of arcuate nucleus?OBJECTIVE: To study the effects of acupuncture on the function of arcuate nucleus of obese rats, and further investigate central nervous functional mechanism of reducing weight by acupuncture.DESIGN: Randomized controlled study based on the experimental animals.SETTING: Acupuncture institute in second clinical medical college of a university of traditional Chinese medicine, and a population management college.MATERIALS: This experiment was carried out in the Acupuncture Institute of Second Clinical Medical College, Nanjing University of Traditional Chinese Medicine between April and October 2002. One-month old male SD rats just in ablactation were selected.METHODS: Rats fed with ordinary wholesome rat-feed were in the normal group. The successfully established experimental obese rats models were randomly divided as control group and acupuncture group with 12 rats in each group. Rats in the acupuncture group were given acupuncture treatment for 14 days, and rats in the normal and control groups were put into rat fixation-machine for 15 minutes every day, lasting for 14 days. Body mass, Lee' s index, body lipid, level of central and peripheral leptin and insulin(INS) as well as the frequency of spontaneous discharge of nerve cell in the arcuate nucleus(ARC) of hypothalamus in obese rats were observed with nervous electrophysiological and nervous biochemical technology before and after acupuncture.MAIN OUTCOME MEASURES: ① Effect of acupuncture on obesity index, fat contents of pericardium, kidney and epididymis of experimental obese rats. ② Effect of acupuncture on the frequency of spontaneous discharge of ARC nerve cell of hypothalamus in obese rats. ③ Effect of acupuncture on the contents of hypothalamic and serum leptin and INS of rats in each groups. ④ Correlation of the frequency of spontaneous discharge of ARC nerve cell of hypothalamus with the level of hypothalamic leptin and INS.RESULTS: The body mass[(517.74±29.35) g], Lee' s index (319.85 ± 3.96) and body fat content of obesity rats [ (13.88 ± 1.32) g] were all significantly higher than those in the normal rats, the differences were significant(P ＜ 0.01); the frequency of spontaneous discharge of nerve cell in ARC of hypothalamus in obese rats [ (3.12 ± 1.92) Hz] were all markedly lower than those of the normal rats[ (8.99 ± 2.71 ) Hz], the differences were significant (P ＜ 0.01 ); the frequency of spontaneous discharge of nerve cell in ARC was negatively correlated with body mass, Lee' s index and body lipid( r = -0. 592, -0. 672, -0. 521 ) . Acupuncture significantly increased the frequency of spontaneous discharge of nerve cell in ARC of hypothalamus in obese rats [(9.75 ±2.02) Hz] as compared with the control group, the differences were significant( P ＜ 0. 01 ).CONCLUSION: The good regulating effect of acupuncture on the function of arcuate nucleus of hypothalamus might be one of mechanisms in the antiobesity of acupuncture.
